Fig. 7.

Locations of SNPs mapped onto human AChE three-dimensional structure of the truncated soluble form containing the N-terminal 547 AChE amino acid residues (see Fig. 1). Synonymous SNPs are indicated by blue amino acid side chains and blue labels, whereas nonsynonymous SNPs are indicated as yellow side chains and yellow labels. The active center serine (Ser203) and Tyr133 are shown in black.
